COVERING THREAD WITH WOOL.

Specification of Letters .Patent No.

To all whom t may concern:

Be it known that I, ANDREW L. FULLER, of Clinton, in the county ofWorcester and State of Massacliusetts,have invented a new and usefulImproved Sliver; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to thedrawings herewith presented and to the letters of reference markedthereon.

The object of my invention is to enable me to make a sliver offtherefuse waste, or short fiber stock, and to at the same time give itstrength enough to be used in the loom.

I am aware that slivers have been made of two materials both cardedtogether', also by placing one between the other after leaving the card,and also by spinning the two together to form a thread of two substancesor dierent qualities of the same. y

My invention di'ers from all these, and consists in placing a core inthe interior or center of the sliver by introducing it into the cardedmaterial as it is delivered bythe comb, and by the combined action ofthecomb and condenser from the sliver around the core. To accomplish this,I attach to the frame of the card (see drawings in which A representsthe last roll, B the comb, C the condenser and D D the rolls) a stud orspindle F to hold a bobbn or ball of the 16,164, dated December 2, 1856.

thread to make the core and pass the end of it (the thread) into thecondenser C with the lber as delivered by the comb B the motion of whichcurles the fibers around the core and the rolls draw the whole throughas condensed and perfect although the twist given is thrown out againand the core will be found in the center or nearly so.

Thus I am enabled to make a sliver capable of being used in the loom anddrawn through by the shut-tle somewhat after the manner of weaving hair,and make all kinds of quilted, waddedor padded goods for variouspurposes, though I do not claim the weaving of such goods, nor the useof wad-` ding in the loom, neither do I claim makingA the sliver of twomaterials 1n order to spin Y a liner around a coarser, or vice versa, asI am aware that is old. But

Vhat I do claim as new and desire to secure by Letters Patent is:

I claim the above described mode of placing the core in the sliver andcovering itv by the combined action of the comb B, and condenser C, soas to produce the sliver above described, and this I claim whether atwist be given to the sliver or not.
